2015-05-28kernel/params: constify struct kernel_param_ops usesLuis R. Rodriguez
Most code already uses consts for the struct kernel_param_ops, sweep the kernel for the last offending stragglers. Other than include/linux/moduleparam.h and kernel/params.c all other changes were generated with the following Coccinelle SmPL patch. Merge conflicts between trees can be handled with Coccinelle. In the future git could get Coccinelle merge support to deal with patch --> fail --> grammar --> Coccinelle --> new patch conflicts automatically for us on patches where the grammar is available and the patch is of high confidence. Consider this a feature request.

2011-11-01lis3lv02d: make regulator API usage unconditionalMark Brown
The regulator API contains a range of features for stubbing itself out when not in use and for transparently restricting the actual effect of regulator API calls where they can't be supported on a particular system so that drivers don't need to individually implement this. Simplify the driver slightly by making use of this idiom. The only in tree user is ecovec24 which does not use the regulator API.

The driver doesn't check the result and directly uses it as some sort of divisor in some places: msleep(lis3->pwron_delay / lis3lv02d_get_odr()); Under this circumstances, this could very well cause the "divide by zero" exception from above. For now, I fixed it the easiest and most obvious way: Check if the result is sane and if it isn't use a sane default instead. I went for "100" in the latter case, simply because /sys/devices/platform/lis3lv02d/rate returns it on a successful boot.

2011-10-04lis3: fix regression of HP DriveGuard with 8bit chipTakashi Iwai
Commit 2a7fade7e03 ("hwmon: lis3: Power on corrections") caused a regression on HP laptops with 8bit chip. Writing CTRL2_BOOT_8B bit seems clearing the BIOS setup, and no proper interrupt for DriveGuard will be triggered any more. Since the init code there is basically only for embedded devices, put a pdata check so that the problematic initialization will be skipped for hp_accel stuff.
